3D Printed Smart Gel Changes Shape When Exposed to Light
Inspired by the color-changing skin of cuttlefish, octopuses and squids, engineers have created a 3D printed smart gel that changes shape when exposed to light, becomes "artificial muscle" and may lead to new military camouflage, soft robotics and flexible displays.

Engineers Print Wearable Sensors Directly on Skin Without Heat
Wearable sensors are evolving from watches and electrodes to bendable devices that provide far more precise biometric measurements and comfort for users. Now, an international team of researchers has taken the evolution one step further by printing sensors directly on human skin without the use of heat.

Microbots to Kill and Clean Biofilms
Biofilms -- microbial communities that form slimy layers on surfaces -- are difficult to treat and remove, often because the microbes release molecules that block the entry of antibiotics and other therapies. Now, researchers have made magnetically propelled microbots derived from tea buds, which they call "T-Budbots," that can dislodge biofilms, release an antibiotic to kill bacteria, and clean away the debris.

Researchers Print, Tune Graphene Sensors to Monitor Food Freshness
Researchers dipped their new, printed sensors into tuna broth and watched the readings. It turned out the sensors - printed with high-resolution aerosol jet printers on a flexible polymer film and tuned to test for histamine, an allergen and indicator of spoiled fish and meat - can detect histamine down to 3.41 parts per million.

Expandable Foam for 3D Printing Large Objects
It's a frustrating limitation of 3D printing: Printed objects must be smaller than the machine making them. Huge machines are impractical for printing large parts because they take up too much space and require excessive time to print. Now, a new material can be used to 3D print small objects that expand upon heating. The foam could find applications in architecture, aerospace and biomedicine.
